Question: Classification of the way of cable fault occurrence Answer: 1. Breakdown fault When the cable is doing preventive test, the hidden place of the cable is broken down due to the effect of higher DC voltage. Such faults are mostly high-resistance flashover faults relative to ground. 2. Problems of line breakdown: Classification of cable failures. Answers: 1. Breakdown failure During the preventive test of the cable, due to the effect of higher DC voltage, the hidden danger of the cable is broken down.
Such faults are mostly high-resistance flashover faults relative to ground. 2. Line breakdown fault This kind of fault is a fault that occurs when the cable runs at the working voltage, and is generally a high-resistance or low-resistance fault between phases or relative to the ground. 1111MicrosoftInternetExplorer402DocumentNotSpecified7.8 ptNormal0.
